Heterostructure 0-10% Au/ZnO samples were synthesized as UV visible-light-driven photocatalysts using sonochemical-deposition method. The 10% Au/ZnO nanocomposites exhibited the highest photocatalytic activity and stability in the photodegradation of methylene blue (MB) aqueous solution under UV visible light irradiation.
Heterostructure 0-10% Au/ZnO samples as UV visible-light-driven photocatalyst were successfully synthesized by sonochemical-deposition method. The 10% heterostructure Au/ZnO nanocomposites show cubic metallic Au nanoparticles with size of 20-50 nm supported on the surface of pure ZnO microparticles. Photocatalytic activities of the heterostructure Au/ZnO nanocomposites were studied through photodegradation of methylene blue (MB) aqueous solution under UV visible light irradiation. The 10% Au/ZnO nanocomposites show the highest photodegradation of MB aqueous solution under UV visible light irradiation with very high stability.
